So, why would she want to deal with her ongoing feud with cast mate
Taylor Armstrong, as well? We've been asking ourselves that same question. After much research, we've discovered the answer is very simple. Kim HATES Taylor.

We left no stone unturned in our Kitty Kelley-like investigation to unearth just why Kim hates Taylor so much. And while we only needed one good reason, we found 10!

Here are the 10 reasons Kim hates Taylor:

1.) The feud started very early on during the cast's first photo shoot together. Taylor believed she should have the comfy seat, but Kim had a few and knew she couldn't stand the whole time. After Andy Cohen (who also likes his cocktails very much) stepped in, Kim got to sit while Taylor stood.

2.) Taylor was shady in Las Vegas.

3.) Taylor once tried to steal everyone's drinks and we all know how Kim feels about her cocktails.

4.) Everyone avoided
Camille Grammer like the plague and poor Kim was stuck talking to her at a party. Meanwhile, Taylor just turned around and snickered about it.

5.) At the premiere party, Taylor and
Kyle Richards knew which camera to look at, but kept it from the other girls.
Adrienne Maloof was on to them, but Kim only discovered the catty trick after seeing the picture below.

6.) In fact, Taylor stood between Kim and Kyle a lot and made it hard for the sisters to remain close.

7.) Kim once tried to tell the other girls that Taylor was a zombie, but no one would listen.

8.) In a point-off, Taylor was the quicker draw and almost pointed Kim to death. Check out the photo finish below.

9.) During the reunion taping, Taylor hid behind
Lisa Vanderpump and toasted to Kim's downfall to her face! We see you, Taylor! We see you.

10.) At the reunion taping and after holding a grudge for months (See No. 1 above), Taylor finally snagged the comfy seat.
